Philips proof-of-concept pictures patients using their thoughts alone or in conjunction with muscles, eye tracking, voice, and touch to send brain commands to an Android tablet that then controls TVs, lighting, medical alerts, and even email, while providing feedback with a wearable display.

This system seems to offer a simple (and stylish) electrode cap for using brain waves to control household functions. It also requires a duration of signalling for an action to occur so that distractions or fleeting thoughts don't cause a wild series of events to unfold. This looks like progress towards a viable device.
Electroencephalography (EEG) is a very interesting subject and it is there for a long time helping neural diagnosis. It is good to see that advancement made in today's technology such as IoT is helping in getting the smart gadgets connected to the "brain waves". Some day in near future, it might not be required to type while chatting on the web...neural oscillations interpreted in language would propagate over the internet...more transparent communication & emotions, rather than hiding something while talking...would be interesting :)
Yes, there are many projects aimed at using brain waves to control the world. Thanks for the link--very interesting. The Philips/Accenture venture is similar. Today it is aimed exclusively at helping paralyzed patients attain a more independent life, but I'm sure it will expand into other areas eventually.
